Objective: This study aimed to investigate the impact of intramuscular B12 on renal anemia among ESRD patients receiving hemodialysis (HD) at El-Najar hospital, Gaza Strip. Patients and Methods: A case-control study conducted, which included 110 healthy controls and 110 HD patients who received B12 on a daily, weekly, and monthly basis over two months. Sociodemographics and current diseases were reported. Serum levels of serum B12, white blood cell (WBC), red blood cell (RBC), hemoglobin (Hb), mean corpuscular volume (MCV), and platelet (PLT) were recorded before and after treatment. Data analysis was conducted using SPSS. Results: Baseline serum B12 level was significantly lower in HD patients compared to controls (362.62 ± 166.40 versus 483.36 ± 115.07 ρg/mL, P<0.001), which significantly improved after vitamin B12 treatment (639.08 ± 362.99 ρg/mL, P<0.001). Additionally, mean WBCs, RBCs, Hb, and PLT levels were significantly increased after treatment (P<0.001). Serum B12 level was positively and significantly (P<0.001) correlated with levels of WBC (r = 0.45), RBC (r = 0.43), Hb (r = 0.39) and PLT (r = 0.51), and negatively correlated with MCV (r = -0.46, P<0.001). Conclusion: Administration of vitamin B12 improves serum B12 levels in HD patients, which was associated with increased WBCs, RBCs, Hb, and PLT levels and decreased MCV levels. Treatment by vitamin B12 can improve HD patients’ renal anemia. Future studies with larger sample sizes and prolonged follow-up are advocated.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41397683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its clinical utility has not yet been approved. Objectives: This study aimed to investigate the possibility of using uNGAL as a predictor of AKI in patients admitted to the ICU. Patients and Methods: This prospective study was conducted on 32 patients admitted to the ICU who had normal creatinine level at the ICU admission and did not fulfill the RIFLE (risk, injury, failure, loss of kidney function, and end-stage kidney disease) criteria. Initially, creatinine level and the sequential organ failure assessment (SOFA) score were recorded. In the first 24 hours of hospitalization, urine samples were taken from patients to assess uNGAL levels. In the following days, creatinine levels and the day of its rise were recorded. The incidence of AKI was assessed based on the RIFLE criteria, and the relationship between the AKI incidence and the uNGAL level at admission was assessed. Results: The mean (SD) of patients’ age was 63 ± 17 years, and 18 patients (56%) were male. The cause of hospitalization was post-cardiac surgery in 21 patients (66%). The median SOFA score of patients was 2.5 at admission. According to the RIFLE criteria, 47% of patients had kidney problems at different stages. The median length of hospital stay was 13 days, while four patients (13%) died. Range and mean (SD) of uNGAL level at admission in all patients was 46.1 to 172.5 ng/mL and 89.94 ± 30.9 ng/mL, respectively, which was not significantly different between the two sexes and between living and deceased patients. Although the mean of uNGAL increased in patients in the risk and injury stage of the RIFLE criteria compared to normal patients, the difference between them was not significant. The increase in uNGAL was directly related to the increase in SOFA score (Spearman’s rho = 0.360, P = 0.043), while its changes was not significantly related to age or creatinine elevation ratio. Conclusion: The findings of our study showed that, in ICU admitted patients, first-day uNGAL level was not helpful in predicting AKI based on the RIFLE criteria.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45503162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to estimate the prevalence and titers of anti-HLA-class I and anti-HLA-class II antibodies in sensitized patients in a kidney transplantation center. The history of the risk factors of sensitization was studied. Patients and Methods: Twenty highly sensitized ESRD patients with a calculated panel-reactive antibody (CPRA) ≥50% were selected, and anti-HLA-I and anti-HLA-II antibodies were assessed in their sera using a single antigen bead (SAB) Luminex assay. Results: The previous history of kidney transplantation was the most critical sensitization risk factor. The results indicated that HLA A*24:02 and DQA1*02:01/DQB1*06:02 were the most frequent antibodies in class I and class II, respectively. Moreover, the mean fluorescence intensity (MFI) levels of anti-HLA class II antibodies were significantly higher than the MFI levels of anti-HLA class I antibodies. Conclusion: According to the findings of this study, matching HLA alleles, particularly class II molecules, can reduce sensitization in the first kidney transplant. A better understanding of the sensitization status of transplant candidates could be gained by examining CPRA values.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44277601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and Methods: An observational study with a cross-sectional approach involving 80 CKD subjects, distributed into stage 3 (n = 20), stage 4 (n = 20), stage 5 non-dialysis (n = 20) and stage 5 dialysis CKD subjects(n = 20), at Wahidin Sudirohusodo hospital and Unhas hospital, Makassar, from April through August 2021.

Results: The average phosphate concentrations at stage 3, stage 4, stage 5 non-dialysis and stage 5 dialysis were 4.14 ± 1.85 mg/dL, 4.17 ± 1.12 mg/dL, 6.43 ± 3.09 md/dL and 5.42 ± 3.09 mg/dL, respectively.

UTI timely diagnosis and treatment is essential to prevent renal failure. Objectives: This study aims to investigate the association of sacral dimples with recurrent UTIs and urodynamic findings in a group of pediatric patients. Patients and Methods: This case-control study was conducted on children aged one month to fifteen years old with recurrent UTIs. The association of sacral dimples with recurrent UTIs and urodynamic findings were studied. Results: In total, 229 patients with recurrent UTIs were recruited. One hundred thirty-one patients were in the case group (with sacral dimple), and 98 patients were in the control group (without sacral dimple). One-hundred and nine children (82.2%) in the case group and 56 children (57.1%) in the control group had abnormal voiding cystourethrography (VCUG) (P<0.001). Forty patients in the case group and 29 patients (29.6%) in the control group had abnormal dimercaptosuccinic acid (DMSA) scan in the first study (P=0.568).

Conclusion: In this study, abnormal uroflowmetry and bladder compliance were significantly more common in children with recurrent UTIs with sacral dimple in comparison to recurrent UTIs in patients without sacral dimple.
